Even though cash is king, there are some real oddities. The new 500 yen coin that is hard to use is in machines is one. The other being the 2000 yen note. The normal denominations are 1000, 5000, 10,000. 2000 yen notes are very rare. For some reason, they seem to hand them out almost exclusively to tourists as they enter the country. Imagine if you gave Scottish five pound notes to everyone coming into the UK in Dover?
